Despite the heroic efforts of Pensacola physicians who risked and sometimes lost their lives treating yellow fever, several factors made control of yellow fever difficultcould do little more than diagnose the disease. Prior to the early 1900s, it There was not generally understood that yellow fever was transmitted not by person-to-person contactno effective treatment.

The first scientific evidence that yellow fever was transmitted by mosquitoes was obtained by Cuban physician and scientist [[Wikipedia:Carlos Finlay|Carlos Finlay]] in 1881, but his research vaccine was not generally accepted developed until a team lead by [[Wikipedia:Walter Reed|Walter Reed]] reached the same conclusion in 19011937.

*[[1822]]
In the epidemic of 1822, most residents of the Pensacola area either fled or were killed. According to one estimate, the population was reduced from about 4000 before the epidemic to about 1400 after; a different estimate appears below. Commerce and industry were almost entirely destroyed.<ref name="bigler"/> Here are a few excerpts from eyewitness accounts of the this epidemic of 1822:<ref>"1822 Yellow Fever" http://genealogytrails.com/fla/escambia/epidemic_1822.html</ref>.
"A terrible epidemic has visited Pensacola... About a hundred and fifty have, in twenty days, been consigned to the tomb, and as many as eighteen have fallen in a single day. Never, perhaps, was a fever more universally fatal, utterly defying the aid of medicine; no instance of a recovery after an attack, has occurred."
"It is impossible to give you an idea of the extent of the calamity which has befallen Pensacola; out of a population of fourteen hundred, which it was said to contain when we arrived, short of four hundred now remain; the rest have either died or made their escape. We are the only American family that remains alive in the place, and there are but very few other Americans here... All our authorities have either died or deserted... You may cast your eyes for hours every day round and not see an individual moving, save the hardened carman with his heavy loaded hearse."

In 1835, yellow fever spread to the Navy Yard and throughout ships in the harbor.<ref name="bigler"/>

This epidemic was introduced by a patient from New Orleans. He and several physicians attending him all died. Members of the family where he was sick also contracted the disease<ref name="choppin"/>.

The 1874 epidemic claimed thousands killed 354 of livesPensacola's 1400 residents.In the belief that the disease was transmitted by day, victims were buried in the cemetery at night by the light of lanterns.<ref>[http://barrierislandgirl.blogspot.com/2006/10/st-michaels-cemetery-history-of.html Zemenick, D.J. "St. Michael's Cemetery - History of Pensacola"]</ref>
Commodore Melanchton B. Woolsey, commandant of the Navy Yard, correctly believed that yellow fever was transmitted by mosquitoes, some years before this was demonstrated scientifically. "He erroneously believed, as others did also, that disease carrying mosquitoes could only fly a few feet high. So Woolsey moved into the third-story cupola. He got his meals, rum (which he claimed was a 'tonic' against the fever) and tobacco for his pipe by lowering a basket on a rope from one of the cupola's windows. One day his servant forgot the rum! Woolsey died soon thereafter."<ref>[http://benefits.military.com/misc/installations/Base_Content.jsp?id=1080 "Military.com Installation Guide"]</ref>Shortly before the epidemic began, Woolsey had received orders to transfer to a northern post, but he had chosen to remain on duty in Pensacola.<ref>[http://famousamericans.net/melanchtontaylorwoolsey/ "Virtual American Biographies"]</ref>.
*[[1882]]
On September 30, 1882, before the epidemic had concluded, the New York Times reported reported 783 cases of yellow fever in Pensacola, including 78 deaths.<ref>[http://query.nytimes.com/gst/abstract.html?res=9401E2DF1F3EE433A25752C0A9669D94639FD7CF "The Yellow Fever Scourge; Rapid Spread of the Disease in Pensacola and Need of Aid" The New York Times, September 30, 1882]</ref> The New York Times also reported that "the state of Alabama has quarantined against Pensacola. Unless some arrangement can be made to avert the disaster, all trains will be withdrawn, and the city will be cut off from mails and supplies."<ref>[http://query.nytimes.com/gst/abstract.html?res=9E07E6DA1E3EE433A25751C0A96F9C94639FD7CF "Yellow Fever's Victims; A Scourge in the South -- A Quarantine Against Pensacola" The New York Times, September 2, 1882]</ref>
In a contemporaneous account of the 1882 epidemic, R.B.S. Hargis, a physician who treated numerous yellow fever cases in Pensacola, reported that at the Pensacola Navy yard and in the adjacent villages of Warrington and Woolsey, with a total population of between 1300 and 1400, there were 167 cases of yellow fever and 33 deaths.
Although some medical authorities at the time correctly realized that yellow fever is not infectious from the sick the the healthy, Dr. Hargis disagreed with this conclusion, based on his personal experience. "My practice taught me... that on leaving an infected ship
I carried the disease in a severe form to my wife, who was far from the infected locality, and who communicated it to my youngest child."
Dr. Hargis had a vague idea that something in the air expedited the transmission of the disease, but did not state that that mosquitoes were involved: "Certain unknown conditions of the atmosphere obtain at times, which favor the reproduction and dissemination of the <i>morbific principle</i>, and when this occurs, no means of disinfection or of staying its progress known to sanitarians are adequate to destroy it, or even mitigate or lessen its potency."
Dr. Hargis reported "exceedingly stringent precautions around our city to prevent refugees communicating the disease."<ref>[http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=2272478 Hargis, R.B.S. "The Pensacola Yellow Fever Epidemic of 1882"]</ref>
